In Christian Doctrine, Milton regards the Holy Spirit as a being inferior to God and Christ, so expressing a discontent with rigid orthodox trinitarianism. Milton works through 12 references to the Holy Spirit in the Old and New Testaments, but gives no explicit definition of the Spirit, while the vagueness of the Spirit's identity points to the unfathomable depths of God's power. As a spiritual gift, the Holy Spirit enables believers to realize Christ's grace and be released from the bondage of the Mosaic Law, thereby gaining true Christian freedom. Free Christians may be bound together through the mediation of the Holy Spirit-it is the Spirit who builds believers up into a textual community and a community of love.
